woke up today with no A/C...

Unit is lifeless. As if a fuse is blown.
(hmm.. maybe I should check the fuse.).

There will be a 12 volt fuse also, often labeled "furnace".

Have you checked the outlet you are plugged into?

Do you have an outlet tester to make sure the shore-power outlet is wired correctly? Are the power-cord wires connected tightly at the buss-bar? No loose connections or signs of a scorched connection (same for the shore-power cord plug).

Where are the fuses generally located on these units if there is one.
I have reset all the breakers already.
